It is known that the risk of developing a second primary respiratory
or digestive tract tumor is high in treated small-cell
lung cancers. The study aims to present a patient with metachronous
small cell and non-small cell lung cancer. Thirteen
years ago, a 78-year-old male patient received chemotherapy
and radiotherapy due to limited-stage small cell cancer in
the right lung. In the 6th year of the follow-up, he underwent
right upper lobectomy due to Stage 2B lung epidermoid
carcinoma. Over the 7 years after lobectomy, he has been
followed without any problem. In small cell lung cancer patients
with a survival more than 2 years, the risk of developing
second primary non-small cell lung cancer is 7-16 times
higher compared to ones who smoke but do not have cancer.
Patients should be followed closely, thus a possible metachronous
tumor could be detected at early stages.
